Each parent gives one copy of the SMN1 gene to a child with SMA. A child who inherits the SMN1 gene from only one parent is unlikely to develop the condition although they may pass the gene on to their children. What are the symptoms and signs of spinal muscular atrophy? Spinal muscular...
What are the causes of spinal muscular atrophy? Most cases of spinal muscular atrophy (SMA) are caused by a mutation in the SMN1 gene. The gene does not produce enough of a protein required for appropriate motor neuron function. Motor neurons die and are unable to convey impulses to the mu...
Spinal Muscular Atrophy Outlook The outlook depends on when symptoms started and how severe they are. If your child hastype 1, a severe form of SMA, they may start having symptoms anywhere from birth to age 6 months. In general, most babies with this type start showing signs of the diseas...

6. Symptoms of infantile spinal muscular atrophy combined with a hitherto not described error in leucine metabolismPediatric Research publishes original papers, invited reviews, and commentaries on the etiologies of diseases of children and disorders of development, extending from molecular biology to ...
Type 0 is the rarest and most severe form of spinal muscular atrophy (SMA), a rare genetic disease that causes muscle weakness and wasting. Like all other main types of SMA— types 1 to 4 — type 0 is caused by mutations in the SMN1 gene, and results in the progressive loss of ...
Objective: To determine the frequency and relative importance of symptoms experienced by patients with spinal and bulbar muscular atrophy (SBMA) and to identify the modifiable factors that have the greatest effect on severity of symptomsBackground: SBMA is an inherited motor neuron disease caused by ...
Spinal Muscular Atrophy This is an inherited condition that affects lower motor neurons. A defect in a gene called SMN1 causes spinal muscular atrophy. This gene makes a protein that protects your motor neurons. Without it, they die. This causes weakness in the upper legs and arms, and in ...
